A racing game was used in urinals to teach drunk people that they weren't sober enough to drive. Once they crashed the car (controlled by their pee) the game would warn you are to drunk to drive. http://www.engadget.com/2007/11/05/urinal-game-banned-by-killjoy-belgium-police/
That's an awesome idea! The game actually looks really good. It's a shame it's been banned though -- I'd imagine water sales would increase dramatically at the venue.
